PAUL BUHL, OF LUBECK, GERMANY.

SKID

No. 923 i87.

Application filed October 5, 1908.

T 0 all whom it may concern:

Be it known that 1, PAUL BUHL, a subject of the German Emperor, and resident of Lubeck, Germany, have invented an Improvement in Skids, of which the following is a specification.

The subject of the present invention relates to improvements in skids which can be used either horizontally or vertically, and are provided with an easily detachable slid or carriage.

Another advantage is that the skids can be folded together.

The accompanying drawing indicates a type of construction of the invention, in which,

Figure 1 is a side view. on Fig. 1. Fig. 3 is a back view to a larger scale. Fig. d is a view of the skids folded together, with carriage removed.

The device consists of two pieces of U iron (1), which form the runway and are connected by strips of iron (3 and 3") hinged at (2) by which means it is made possible to fold the two pieces (1) together. At the back end of the U-iron, a connecting piece (5) is pivoted at 1). This connecting piece (5) engages by means of a slot with a.bolt (6) fixed to the other U-iron, and serves to hold the skids open. This connecting piece, when the skids are to be folded together, is swung back to the point (7) and hooked onto the bolt (8). The carriage (9) consists of a frame constructed of U-iron, and mounted on four rollers (10), the latter being guided in the U-iron (1) in such a way that it is impossible for the carriage (9) to fall out, as the pulleys run in the channels of the U-iron. A fork (11) is firmly fixed to the lowest or rearmost hinge (3 and 3 and carries a pulley (12), over which the endless chain (13) is guided. This chain is actuated by the chain wheel (15) on the axle (14). The chain Wheel is mounted on the one hand in a support (16) 011 the U-iron (1), and also in an arm (17) which is also fixed to this U-iron (1). The axle (14) is fitted with ratchet wheel (18), pawl (19) and a crank (20). A hook (21) is fixed to the carriage and is put into engagement with the chain when it is desired to actuate the carriage. As soon as the carriage has been raised or moved forward, the hook (21) can be disengaged again and the carriage can be let down without turning back.

The advantage of this device over others Fig. 2 is a plan Specification of Letters Patent.

lies therein that one need no longer raise the pawl, as is necessary in other types. hen using other kinds, it very often happens that the operator forgets to put the pawl in again and an accident is the result. Another ad vantage is that much time is saved by obviating the necessity for turning backward. The U-iron pieces (1) are hook shaped at their front end, so that the skids can be firmly attached to the wagon. When the skids are no longer required, the wagon is pushed out at the front end, the connecting strap (5) is swung around and the U-iron pieces (1) are folded together, (Fig. i) and pushed under the truck. The slid or carriage can "then be stored away on or under the latter.

Having fully described my invention, what I claim and desire to secure by Letters Patent isz- 1. Skids, comprising in combination, two U-iron pieces (1), iron bars (3 and 3*) connecting said U-irons, a connecting piece (5) pivoted to one of said pieces (1), a bolt (6) fixed to the second piece (1), said connecting piece (5) engaging by means of a slot with said. bolt (6), a carriage (9), rollers (10) on which said carriage is mounted, said rollers running in the channels of said U-iron, a fork (11) fixed to the farthest of said hinges (3 3 a pulley (12) in said fork, an endless chain (13) guided over said pulley, an axle (14) mounted in supports, a chain wheel (15) on said axle, over which said chain passes, a crank (20) on said axle for driving said chain wheel and chain, substantially as described and shown.

2. Skids, comprising in combination, two U-iron pieces (1) iron bars (3 3) connecting said U-irons, said bars being hinged so that the two U-irons can be folded together, a con necting piece (5) pivoted to one of said pieces (1), a bolt (6) fixed to the second piece (1), said connecting piece (5) engaging by means of a slot with said bolt (6), a carriage (9), rollers (10) on which said carriage is mounted, said rollers running in the channels of said U-iron, a fork (11) fixed to the farthest of said hinges (3 3 a pulley (12) in said fork, an endless chain (13) guided over said pulley, an axle (14) mounted in supports, a chain wheel (15) on said axle, over which said chain wheel passes, a crank (20) on said axle for driving said chain and chain wheel, substantially as described and shown.

3. Skids, comprising in combination, two

LJ-iron pieces (1) iron bars (3 3') connecting said U-iron pieces, said bars being hinged so that the two U-irons can be folded together, a connecting piece (5) pivoted to one of said pieces (1), a bolt (6) fixed to the second piece (1) said connecting piece (5) engaging by means of a slot with said bolt (6), a carriage (9), rollers (10) on which said carriage is mounted, said rollers running in the cilannels of the U-iron, a fork (11) fixed to the farthest of said hinges (3, 3 a pulley (12) in said fork, an endless chain (13) guided over said pulley, an axle (14) mounted in sup ports, a chain wheel (15) on said axle, over which said chain wheel passes, a crank (20) on said axle for driving said chain wheel and chain, a hook (21) on said carriage which can be put into engagement with the moving chain whereby the carriage is moved, substantially as described and shown.

4. Skids, comprising in combination, two U-iron pieces (1) iron bars (3, 3*) connecting said U-iron pieces, said bars being hinged so that the two U-irons can be folded together, a connecting piece (5) pivoted to one of said pieces (1), a bolt (6) fixed to the second piece l (1) said connecting piece (5) engaging by means of a slot with said bolt (6), a carriage (9), rollers (10) on which said carriage is mounted, said rollers running in the channels of the U-iron, a fork (11) fixed to the farthest of said hinges (3 3 a pulley (12) in said fork, an endless chain (13) guided over said pulley, an axle (14) mounted in supports, a chain wheel (15) on said axle, over which said chain wheel passes, a crank (20) on said carriage which can be put into engagement with the moving chain where by the carriage is moved, a ratchet wheel (18) on said shaft (14), a pawl (19) on said wheel, by which means the necessity of turning the crankbackward is obviated, substantially as described and shown, and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing I witnesses.
